Visitors to the Dublin Zoo got a good lesson in what happens when you wake up a tiger that doesn't want to be woken up. In a video of a tiger enclosure uploaded to YouTube on April 9, one tiger walks up to a sleeping tiger and instead of just politely asking it—"Hey. Pssst. Are you sleeping or dead?"—awake tiger tries to play the game attack sleeping tiger. The now-all-of-a-sudden-not-sleeping tiger wakes up in full combat mode (like some teenagers), swatting angrily at its waker-upper.
Well, really. What did you expect, tiger? Ever hear the expression, "Let sleeping tigers lie?" No? That's because it's made up. But still totally relevant.
In a different video from 2015, YouTube user "BigCatDerek" accidentally wakes a sleeping tiger, but after explaining his side of the story, the tiger lets him off the hook. THIS TIME.
And this video from 2011 shows a tiger waking up in a much better mood, but it's clearly stoned.
The lesson here? Don't wake a tiger up unless it's on your couch. Or something like that.
